Purpose Of Review: This review summarizes the role of incidentally and non-incidentally discovered coronary artery calcification (CAC) and the evolving role of non-coronary artery calcification in atherosclerotic cardiovascular disease (ASCVD) risk assessment. Additionally, this review explores the emerging use of artificial intelligence (AI), machine learning (ML), radiomics, and natural language processing (NLP) for automated detection, quantification, and communication of these incidentally discovered findings.

Recent Findings: This review summarizes recent findings in the space, including the development of various AI/ML-based approaches for automated calcification quantification and detection.

Direct oral anticoagulants have a dose-dependent increased bleeding risk which limits use in certain populations. Studies in both animals and humans with inherited variations in factor XI levels provide a theoretical basis for a drug target capable of addressing current unmet needs. Milvexian is an oral factor XIa inhibitor that has the potential to provide robust anticoagulant effect without increased bleeding compared with current standard of care.

Article Synopsis
  • This review highlights how Artificial Intelligence (AI) improves the assessment of atherosclerotic cardiovascular disease (ASCVD) risk, opportunistic screening, and guideline adherence by analyzing both unstructured clinical and patient-generated data.
  • Recent findings indicate that AI models outperform traditional risk scores in evaluating individual ASCVD risk and can automatically detect risk markers, like coronary artery calcium (CAC), using various imaging techniques.
  • AI applications are valuable for preventing and managing ASCVD, and they can enhance patient education, but successful integration into clinical practice requires careful regulation and structured clinical pathways.

Coronary artery calcium (CAC) scoring is a powerful tool for atherosclerotic cardiovascular disease risk stratification. The nongated, noncontrast chest computed tomography scan (NCCT) has emerged as a source of CAC characterization with tremendous potential due to the high volume of NCCT scans. Application of incidental CAC characterization from NCCT has raised questions around score accuracy, standardization of methodology including the possibility of deep learning to automate the process, and the risk stratification potential of an NCCT-derived score.

Objectives: Thyroglossal duct cyst (TGDC) is the most common pediatric congenital neck mass. The Sistrunk procedure is the standard method of excision and is associated with low rates of recurrence. This study aimed to review our institution's outcomes following the Sistrunk procedure, specifically the rates of wound complications and cyst recurrence.

Background: Implantable cardioverter-defibrillator (ICD) therapy is recommended to reduce mortality risk in patients with heart failure with reduced ejection fraction (HFrEF). Frailty is common among patients with HFrEF and is associated with increased mortality risk. Whether the therapeutic efficacy of ICD is consistent among frail and nonfrail patients with HFrEF remains unclear.

Background: Considerable research supports an important role for the microbiome and/or microbiome-host immune system interactions in the pathogenesis of inflammatory bowel disease (IBD). Consequently, microbiota-modulating interventions, such as fecal microbiota transplantation (FMT), have attracted interest in the management of IBD, including ulcerative colitis (UC).

Summary: While the clinical response to FMT in UC has varied between different studies, results to date may offer guidance toward optimal use of FMT.

Significance: An unmet need is recognized for early detection and diagnosis of neurological diseases. Many psychological markers emerge years after disease onset. Mitochondrial dysfunction and corresponding neurodegeneration occur before onset of large-scale cell and tissue pathology.

Optical coherence tomography allows for various measurements of skin but the utility of the device in determining properties of normal and wounded skin in diabetic patients is unknown. This single-site, non-randomized, observational study used an optical coherence tomography device to acquire skin images at 1305 nm, creating real-time image of 17 patient's skin and wounds 1 to 2 mm under the skin surface. Vertical B-scan, en-face and 3-D images were produced to calculate surface and dermal-epidermal junction roughness, the optical attenuation coefficient, a measure of light absorption and scattering, and blood flow metrics.

Objectives: The skin aging exposome encompasses internal and external factors that contribute to clinical signs of facial aging. Aging skin can be characterized by distinctive features such as wrinkles, lentigines, elastosis, and roughness. Optical coherence tomography (OCT) is capable of noninvasively measuring skin characteristics.

Introduction: Tissue expansion (TE) in pediatric surgery provides vascularized tissue to attain functional and esthetic goals in a broad range of reconstructive procedures. Our study evaluates the demographic, operative, and short-term outcomes of TE in pediatric patients utilizing the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database and highlights factors associated with postoperative complications.

Materials And Methods: Retrospective review of a large multicenter database of 402 pediatric patients that underwent TE within the NSQIP-P database from 2013 to 2020 at freestanding general acute care children's hospitals, children's hospitals within a larger hospital, specialty children's hospitals, or general acute care hospitals with a pediatric wing.

The goal of this study was to evaluate the temporal and spatial pattern of wound healing following UV corneal cross-linking (CXL) using 3-dimensional (3-D) confocal imaging in vivo. Using a modified Heidelberg Retinal Tomograph with Rostock Corneal Module confocal microscope, we performed 3-D scans on two patients at multiple time points after CXL. Patient 1 showed a normal post-CXL wound healing response, with initial subbasal nerve loss and keratocyte apoptosis in the anterior stroma, followed by partial restoration of both the nerve plexus and stromal keratocytes by 6 months.
